You might need to up your mouse and keyboard speeds in windows- I am not sure where to find them now- use start search and type in keyboard or mouse and up settings. First things I do after install os and before gaming is id up my keyboard and mouse speeds in windows- or can seem like lag or slow response in some games..
From game you might have to up mouse speeds or menus are slow- but can make your movements in game and aiming faster- if not to fast.. I try and hit a balance to speed up menus- but to fast in game can be a head ake sometimes..
** This is how I have mine set as defaults..>
Also just plugging in or unplug re plug mouse or keyboard might not work like that- you may need to reboot windows before it see the mouse or keyboard or it might not work.
